Can you add attributes to classes that inherit attributes from others?

Question

Eg. If I want to add an attribute 'breed' to dogs, could I do that?

Answer 1

Yes

Answer 2

Yes, I read that there are 2 ways to do this. Let's say we want to add 2 attributes "size" and "chaseCat" to Dog class which already inherits "name" and "color" from Animal class:

class Animal: 
    def __init__(self, name, color):
        self.name = name
        self.color = color

class Cat(Animal):
    def purr(self):
        print("Purr...")

class Dog(Animal):

    def __init__(self, name, color, size, chaseCat):
        Animal.__init__(self, name, color)
        # alternative approach:
        # super().__init__(name, color)
        self.size = size
        self.chaseCat = chaseCat

    def bark(self):
        print ("Woof!")     

fido = Dog("Fido", "brown", "big", "likes to chase cats")
print(fido.color)
fido.bark()

print(fido.size)
print(fido.chaseCat)

The result of this code is:

brown
Woof!
big
likes to chase cats

Answer 3

yes,derived class have attributes of base class,and can also have its own attributes.
